Is there any special preparation needed?

There is no special preparation needed. You should eat a normal meal before coming to the lab. To ensure the best results please do not use moisturizers or lotions on your skin and ensure that your hair is clean and free of oils or gel on the day or your test. Please do not use scented products as this is a fragrance-free area.


What happens during an Overnight Sleep Study?

During your sleep, the lab technicians will monitor your brain activity, leg  muscle activity, chin muscle tone, eye muscle movement, heart function, breathing patterns and blood oxygen saturation.  Some optional testing may be done such as carbon dioxide levels. 

All monitoring is done by attaching small metal discs (electrodes) to the surface of the skin.  In order to obtain the best results, electrodes need to be placed on a clean scalp.  Please ensure your hair is clean, dry, and free of oils or gels on the day of your test. 

You will be awakened at 6am and the electrodes will be removed.  Since they are applied with water/soluble paste and tape, removal is quick and easy.  There is one public shower in the unit available for use. You can expect to be discharged around 6:30am.   


What happens during a MSLT - Multiple Sleep Latency Test?

The doctor may wish to also do sleep testing the day after your overnight study. This is called a multiple sleep latency test and consists of four chances to nap at two hour intervals. This test helps to document the extent of daytime sleepiness. If an MSLT is required you will be notified when your overnight study is booked.


What if I have Special Needs?

Staff are sleep technologists and are unable to provide medical care for special needs. 

Staff will need notification in advance if you use;

  • Wheelchair
  • Oxygen
  • Catheters or any tube drainage
  • Ostomy care
  • Any other special needs

Note: Supplies for these special needs are  not  available in the Sleep & Apnea Assessment Unit


Are meals provided?

Please eat a normal meal before coming to the test. We do not provide meals or snacks. If you wish to bring your own snacks, a fridge is available for storage.


What about my medications?

Patients are required to bring all their medications along with a list of all their medications and their dosages. Unless otherwise stated, patients should continue to take all their medications as normal (including over the counter medications).

Note: Staff of the Sleep & Apnea Assessment Unit are technologists/technicians and are not able to administer/provide medications.


When will I get my test results?

Your test result will be analyzed in the lab and a written report will be sent to the physician who referred you for the sleep study. This normally takes two to three weeks. The Sleep & Apnea Assessment Unit staff are unable to provide you with test results. Please contact your referring physician should you have questions about your results.


What if I need to cancel or reschedule my appointment?

24 hours notice is required to cancel or reschedule an appointment. If you do not provide 24 hours notice or if you miss your scheduled appointment the Sleep Medicine Associates will bill you $100 fee.
